To all whom it may co'nccwn Be it known that 1', THORWALD B soN, acitizen of the United States, and dent of Omaha, in the county ofDouglas and have invented certain new and useu1 Improvements in Elect-rers for Carburet'ei's, of Which the follow is a specification.

My invention relates to cerbui'eters such hnstion engines for charge byvaporize such as gesolenew It is the ob vention to movie elect! ted theion e; end; of 2 i; Ibiis an opening; 111 i n (he neeig end i'einex'ahiy above tn-o a State of Nebraska,

10 as are used in connect readily attachable to the bowl or against theend of the core. The lower end of the screw is extended beyond the nut17 to form a b inding-post on which is screwed a knurled bindingnut 18adapted to hold the end oi a wire between the same and the nut 17.

The heating-coil formed by the wire is supplied with electrical energyfrom a storage battery 19, or other suitable means, one terminalthereot' being connected'by a wire 20 with the screw 16, and the otherterminal of the battery or generator being suitably connected by a wire21 with the plug 11 or any part ofthe casing, carbureter or engine whichis in electrical connection with said plug. Any suitable switch 22 isprovided for controlling the heating circuit.

The operation of the device will be readily understood. The wire 15 isso proportioned that when the circuit through the same is closed byoperation or" the switch 22, the coil will be almostinstantly heated bythe electric current flowing therein, and the heat of the coil will becommunicated to the oil surrounding the coil within the hood 6. The

heated oil, being lighter than an equal volume v thereof at lowertemperature will rise up through the hood and the extension-tube 9, thuspassing into the upper part of the bowl 3, while the cooler oil from thelower part of the bowl will iiow downwardly through the neclr of thecasing, around the outside of the hood 6, and passing through theopenings 10 at the lower end of the hood, will come into contact withthe heated coil. Thus there will be caused a constant and rapidcirculation of the oil through the heating device, so that in a veryshort time the entire body of oil from the bowl 3 will be heated to thedesired temperature at which vaporization thereof will readily occurwhen it is drawn from the bowl or float-chamber to the charge-formingdevices. It should be noted that. owing to the arrangement of the wire15 in the thread-grooves of the insulating core, loosening of the wiredue to the expansion thereof when heated cannot result indisarrangeznent or" the coil and short-circuiting of parts thereof bytwo or more of the turns coming into contact with each other.

New, having descfibed in invention, what I claim and desire to secure bLetters Pat- .r-portion connected with the lower par of said receptacle,a hood disposed in said casing in spaced relation to the walls thereofand having an extension-tube passing up through the neck-portion of thecasing in spaced relation thereto and terminating within the receptacle,and an electrical heating element disposed in said hood so as to be incontact with a current of oil flowing from the receptacle downwardlyaround the hood and extension-tube and upwardly through the same.

' 2. In a device of the class described, the combination with acarburetor, of a casing secured to the lower end thereof andcommunicating therewith, a heating element within the casing, a hoodencircling the heating element and provided with a circulating pipeextending into the carbureter, said hood having circulating openingstherethrough adjacent its lower end whereby the gasolene which is heatedby the heating element will rise through the circulating pipe and intothe carbureter and cold gasolene will descend into said casing aroundthe pipe and hood.

3. An oilheating device for carburetors. comprising a casing having atubular upper portion adapted for connection with the lower part of theoil-receptacle of a carbureter so that oil from the receptacle may flowdown through said tubular portion to fill the casing, an electricalheating element disposed in the lower part of the casing, means forconnecting said heating element with a source of electrical energy, anda hood arranged around the heating element and extending therefromthrough the tubular upper portion of the casing in spaced relationthereto, said hood adapted to direct heated oil up through said portionof the casing and prevent said heated oil from mingling with the oildescending from the receptacle into the casing.

at. In a heater for carbureters, the combination with,-a"carbureterhaving a gasolene-contain'ing chamber, of a casing secured thereto andcommunicating therewith, a heating element within the casing, and meanswithin the casing forming a plurality of circulating passagescommunicating with the gasolene-containing chamber whereby the heatingor the gasolene will cause it to circulate from the casing to thechamber through one passage and from the chamber back to the casingagain through another passage.
